What is the image of the moon in Li Bai's Silent Night Thinking?

"Silent Night Thinking" has no strange and novel imagination, no exquisite and gorgeous rhetoric, but only uses narrative style to write the homesickness of distant guests. However, it is meaningful and intriguing, and has attracted readers so widely for thousands of years. From "doubt" to "looking up" and from "looking up" to "bowing down", the whole poem vividly reveals the poet's inner activities, vividly outlines a vivid picture of homesickness on a moonlit night, and expresses the author's feelings of homesickness on a silent moonlit night. Guests can't sleep in the middle of the night, have a short dream.
